So, what are you looking at here?This is an optical phenomenon known as anticrepuscular rays. On the right (slightly blocked by trees) is the western horizon, and on the left, the eastern horizon. When the sun set on the right, there were a few clouds on the horizon. These clouds blocked some of the sun's light, creating these massive rays/shadows. The shadows were well-defined (thanks to the assistance of some sunset-lit clouds), and therefore extended all the way to the left. On the left, they appear to converge at a point called the "antisolar point." This, however, is simply an optical illusion, as the rays are actually parallel.

This came out beautifully. What do you use to do your panorama shots? Just a tripod and Photoshop (or similar)? Or stitch it yourself? I've never tried a shot like this before. Must give it a go. It must have been eerie to see this in the skies - fantastic!

Stunning photo. I love the sharp crisp image on the right that seems to fade as you pan to the left. It gives it a very smooth feeling. I love your work so much. Thanks for sharing such great talented photography.

Thanks! Me neither. I've never seen them solidly connect all the way across the sky like that. I believe this is because that instead of being cast into hazy air (like most anticrepusculars) these were actually physical shadows on some higher sunlit clouds
